Having started playing guitar at the age of 8, The Rock and Roll Hall of Fame member was part of Elvis' original band, the Blue Moon Boys, and continued to work with Presley into superstardom.

Songs that Moore contributed to include Presley’s first hit, “That’s All Right (Mama),” as well as popular tunes "Heartbreak Hotel" and "Hound Dog.”

Phillips Recording Service engineer Matt Ross-Spang, a friend of Moore’s, wrote on Instagram, "We lost one of the finest people I have ever met today. The guitarist that changed the world ... especially mine; I hope you don't mind if I keep stealing your licks."
